Hi everybody,
I want to wrote a function that receives another function as parameter that will be used as a Callback. Well, better a bit of code than thousand words:
class TreeNode {
...
function Traverse ( CallBack ) {
$rtn = CallBack ($this);
foreach ($this->Sons as $Son) {
$Son->Traverse ( CallBack );
}
return $rtn;
}
...
}And later I'll do something as:
function CallBack ( $Node ) {
echo $Node->Name;
}$MyTreeNode->Traverse ( CallBack );
...
Hope you understand what I'm trying to do. Can it be done as is or am I on the wrong way?
Thx. a million in advance,
